Most head trauma involves injuries that are minor and don't require hospitalization. However, call 911 or your local emergency number if any of the following signs or symptoms are apparent:
Severe head or facial bleeding
Bleeding from the nose or ears
Severe headache
Change in level of consciousness for more than a few seconds
Black-and-blue discoloration below the eyes or behind the ears
Cessation of breathing
Confusion
Loss of balance
Weakness or an inability to use an arm or leg
Unequal pupil size
Repeated vomiting
Slurred speech
Seizures
If severe head trauma occurs:
Keep the person still. Until medical help arrives, keep the injured person lying down and quiet, with the head and shoulders slightly elevated. Don't move the person unless necessary, and avoid moving the person's neck.
Stop any bleeding. Apply firm pressure to the wound with sterile gauze or a clean cloth. But don't apply direct pressure to the wound if you suspect a skull fracture.
Watch for changes in breathing and alertness. If the person shows no signs of circulation (breathing, coughing or movement), begin CPR.
